“…83 Diesel Engine -Since Combustion Engine is the most expensive part of the Truck , therefore we need to give it some importance 84 Should Eddy Breakup Model be used by the intermixing of cold reactants with hot combustion products or should a " ame surface density transport equation" be used against differing levels of engine load , where errors against the mean effective pressure , % of indicated e ciency, % of maximum cylinder pressure and how does a difference even for delay in 1 CAD ( Crank angle degree) matter . 85 Should exhaust gas be used to meet the load of the engine while it is being blown down or emptied out when air pressure is controlled through a "late intake valve" 86 .…”

This paper addresses the key issues that go into the making of a heavy truck wherein steel made parts are used in the making of a chassis , so here the challenge for both for the bodyframe designer of the automobile industry and the sheet metal designer of the steel industry to come up with solutions that not only addresses problems relating to the lowering of the weight but also making it strong enough to bear enough loads taking into account changes in materials used , kinematics – differences in body angles that affects the velocity of the actions directed , how parts connected not only in the truck but also in the processes followed including changes in design and thereafter the prototypes to be tried out in the face of oncoming changes . A pentagonal framework that includes open cost modelling as well a business model that talks of creating a value streams in consonance with the changes for the uncertain future has been included.

“…There have been many studies to improve the intake system. [1][2][3][4][5] The swirl motion can be improved by improving the combustion chamber design [6][7][8][9] or by improving the inlet port design. [10][11][12] One of these improvements is to increase the swirl motion of incylinder flow.…”

In this paper, we proposed a method to increase the mixing performance of gasoline and intake air by attaching a helical-spiral shroud to the intake valve. The effect of the height and revolution number of helical-spiral shroud on the generation of swirl in the engine cylinder are analyzed. The height is 20 and 25 mm, and the revolution number is changed to 1 and 1.5 turns. A three-dimensional simulation model using the shear stress transport k–ω model is used as the turbulence model to predict the air flow characteristics through the intake valve and engine cylinder in the intake and compression strokes. As a result, the helical-spiral shroud intake valve (HSSIV) generally increases the swirl ratio compared to the general valve, and the swirl ratio in the HSSIV with a height of 20 mm and revolution number of one turn has a maximum value of 77 around 90CAD. It also shows that HSSIV has little effect on the volumetric efficiency reduction while increasing the swirl ratio from different geometrical properties than the conventional shroud valves.
